Russian warplanes have carried out the second consecutive air strikes in Syria using the Hamadan airbase in western Iran, this time the Su-34 fighter bombers were utilized to hit ISIL targets in the Syrian province of Deir ez-Zor.
The jets dropped OFAB-500 fragmentation bombs on two command centers and two training camps.
If you look at 0:27 of the video, the bombs (look like cluster bombs to me) hit the underside of the Su-34. In my experience, that is bad.
